secured to adjacent box parts.

It is a further object to provide a connecting method for this purpose which may be readily practiced by hand and without using any special- 1y constructed tool or mechanical appliance.

It is a further object of the invention to provide a method of connecting a. bight to a box binding wire.

It is a further object of the invention to provide a method of equipping a box binding wire with a separately formed bight.

The method will be described by reference to the accompanying drawings, in which:-

Figure 1 is a perspective view of one form of wire-connecting means employed in practicing the invention.

Fig. 2 is a perspective view of a wirebound box showing the manner in which the connecting means is secured to each end of each encircling wire binding and the two adjacent connecting means interengaged to connect the wire ends and complete the continuity of the wire binding. In said figure, one of the connections is shown in an intermediate stage of the connecting operation while the remaining connections are shown in their completed position.

Figs. 3, 4 and 5 are enlarged perspective views of a box part with the wire stapled thereto and showing the manner in which the illustrative connecting means is secured to the wire end.

As conducive to a. better understanding of this invention it may be noted that the ends of box encircling wire bindings have been connected in various ways to complete the continuity of the wire binding. For example, the ends of such wires have been intertwisted in the manner disclosed in U. S. Patent to Bauwens No. 1,469,711; have been connected by forming interengageable loops on the ends of the wires as shown in U. S. patent to Inwood No. 1,332,728; and have also been connected by bending the ends of the wires to form bights and then driving the ends of the wire into the box parts to perpetuate the bights, as shown in U. S. patent to Rosenmund No. 1,933,030.

The intertwisting of the ends of the wire as shown in said patent to Bauwens is objectionable because the connection cannot readily be broken without cutting the binding wire, thus rendering the box unfit for a second use. The formation of loops on the ends of the wire as shown in said Inwood patent requires the use of a machine such as that shown in said Inwood patent. Likewise the formation of bights on the ends of 5 the wire in the manner shown in said Rosenmund patent requires the use of a machine for forming and perpetuating the bight as shown in U. S. patent to Rosenmund No. 1,933,031 of October 31, 1933.

The present invention is intended to eliminate the objections to the intertwisted connection of the Bauwens patent and to provide an interengageable fastener for the wire ends which may be readily applied to the wire ends, thus eliminating the necessity of using expensive machinery for forming loops or bights on the ends of the wire bindings. The fastening or connecting means of this invention is inexpensive to manufacture and may be made up in large quantities and carried in stock by the box user and applied to the wire ends without employing any special tools or machinery.

Referring to Fig. 1, the fastening or connecting means of this invention consists of a piece of wire bent to form a loop or bight I, and having the ends of the legs of the bight coiled as shown at 2 and 3 to leave openings 4 and 5 respectively through which the binding wire may be inserted in the manner hereinafter described to connect the fastening means to the binding wire.

As shown in Fig. 2, one such fastening means is connected to each end of each binding wire on the box, so that one such fastening means may be passed through the other and bent down against the side of the box, as shown.

The manner of securing the fastening means to the end of a wire stapled to a box part is illustrated in Figs. 3, 4 and 5. Referring to Fig. 3, the box part is designated 6, the wire secured to the box part is designated I, and the staples which secure the wire 1 to the box part 6 are desig nated 8.

To secure the fastening means to the wire I the coil 8 of the fastening means is slipped over the end of the binding wire I, as shown in Fig. 3. The upper end of the binding wire I which extends above the coil 3 is then bent into the form of a semi-loop, as shown in Fig. 4, to bring the end of the wire I directly over the opening 4 in the coil 2. The fastening or connecting device is then raised, forcing the end of the wire 1 into or through the opening 4 in the cofl 2, as shown in Fig. 5.

The connection between the fastening means and the binding wire '1, shown in Fig. 5, securely connects the two. Increased pull or strain on the connection tightens the connection, due to the fact that the wire end passes upwardly through the coil 3 and is then bent to pass downwardly through the coil 2. The bend in the wire between the two coils, plus the fact that the two legs of the bend are held respectively by the coils 2 and 3, prevents the wire I from pulling away from the fastening or connecting means.

When adjacent wire ends have each been supplied with the fastening or connecting means of this invention in the manner shown in Figs. 3, 4 and 5, two such fastening means may be hooked one through the other to connect the wire ends, as shown in Fig. 2.

While the bend in the wire I, as shown in Fig.1,

may be made by hand without any sort of tool or mechanical appliance, it is usual in practice to employ an ordinary pair of pliers to make this bend in the wire.

While the pair of fastening or connecting means of this invention may be inter-engaged or hooked together by hand, it is usual to employ a. simple tool for this operation.

While the fastening or connecting means of this invention may be used as the initial connecting means for the ends of a box binding wire, it may also be used as a secondary or repair" connecting means for boxes which have initially been provided with bights or loops by machinery, as shown in said Inwood and Rosenmund patents, and which bights have been broken or otherwise rendered unfit for use. In providing wire ends with loops or bights by machinery, occasionally one of the loops or bights is defective. When this happens the fastening or connecting means of this invention may be substituted for the defective loop or bight, thereby saving a box which would otherwise be discarded as a cripple.

The fastening or connecting means and method of this invention may also be used to repair wirebound boxes the wires of which have been broken or severed.

It should be noted that this invention provides for the first time a means and method of securing a separate and independent bight to the end of a box binding wire.

It will be understood thatthe invention is not to be limited to the illustrative embodiment, as the inventive features may be variously embodied and used in various combinations as defined in the sub-joined claims.

This application is a division of my copending application Serial No. 734,974 filed July 13, 1934.

I claim:

1. The method of equipping a wired box part with fastening means which consists in bending a piece of wire to form a U-shaped bight, coiling each end of the piece of wire to provide an enclosed opening within the coil through which the wire on the box part may be passed, and passing the wire on the box. part upwardly through the opening in one coil and downwardly through the opening in the other coil. 10

2. The method of equipping a wired box part with fastening means which consists in bending a piece of wire to form a bight, bending each end or the piece of wire to provide an enclosed opening through which the wire on the box part may be 15 passed, and passing the wire on, the box part upwardly through one opening and downwardly through the other opening.

3. The method of equipping a wired box part with fastening means which consists in bending 0 a piece of wire to form a U-shaped bight, coiling each end of the piece of wire to provide an enclosed opening within the coil through which the wire on the box part may be passed, slipping one coil over the wire on the box part, bending the 25 wire on the box part to bring its end over the opening in the other coil, and raising the U- shaped bight to cause the wire on the box part to pass into the opening in the other coil.

4. The method of completing the continuity of a box encircling flexible binder which consists in forming two flexible metal bights as separate articles, connecting one of said bights to one end of the flexible binder and the other of said bights to the other end of the flexible binder, and hooking one bight through the other.
